According to Andrew Linden, commenting on what has become something of a heated JIRA, SVC-7305, a fix for the PRIM_PHYSICS breakage was rolled out to the three main RC channels (BlueSteel, Magnum and Le Tigre) today.
The breakage, which impacts the PRIM_PHYSICS parameter of llSetPrimitiveParams impacts a wide range of scripted moving objects in Second Life and has caused considerable consternation amount content creators. With vehicles, animals and other items effectively broken, they’ve faced either having to wait for the issue to be sorted and / or re-scripting their products while still having many hundreds – if not thousands – running amok or stalled around the grid – something that apparently left one creator of automated scripted vehicles stuck with a three-day account suspension.
If all goes well – and initial feedback so far is that the fix is working on the Magnum and Le Tigre RC channels without incident – then the fix should find is way onto the rest of the grid during the main updates next Tuesday (assuming one of the RC channels gets promoted to the main release channel at that time).
